QA/G-5i will provide guidance on data quality indicators (DQIs), including the PARRC parameters (i.e., precision, accuracy, reproducibility, representativeness, and comparability) and how they fit into the implementation of the DQO process. The guidance discusses the role of DQIs in sampling and analytical measurements.

QA/G-8 provides non-mandatory guidance to assist users in verifying and validating environmental data. The guidance discusses alternative approaches to data validation, including examples of statistics-based validation techniques, and options for verifying that the validated data satisfy relevant claims about their authenticity and quality.

QA/R-2 is the policy document containing the specifications and requirements for Quality Management Plans (QMPs) for organizations with which EPA has extramural agreements. The document has been finalized and replaces QAMS-004/80. R-2 parallels the implementation requirements for QMPs contained in the EPA Quality Manual for Environmental Programs (EPA Order 5360.1), an internal policy manual.

QA/G-5 provides guidance on developing Quality Assurance Project Plans (QAPPs) that will meet EPA expectations and requirements. This document provides a linkage between the DQO process and the QAPP. It contains tips, advice, and case studies to help users develop improved QAPPs.
